The Hypericum needs planting out, or putting in a much larger pot - if its H. 'Hidcote' it will get large and is semi evergreen, so choose your spot carefully. Remove any dead or dying growth when you repot/plant. The Cotinus in the bottom picture (C. coggygria 'Royal Purple' is probably the variety) is another large shrub, deciduous, and needs to come out of that pot asap, its much too small for it. If the middle one is Philadelphus, that's another biggie, needing a fair bit of room in the ground, again deciduous. Not certain it is Philadelphus, but can't think of anything else it might be.
